Abstract

An active monitoring and crash mitigation system and method for race vehicles. Various sensors are connected directly or wirelessly as inputs to a control module that monitors vehicle and track characteristics to determine if an accident is imminent or has occurred. Programmable criteria in the control module determine whether corrective action is needed and the best course of action for avoiding hazards. Corrective action is achieved by triggering devices that alter the vehicle'"'"'s speed, lift forces, and down forces. The corrective actions force the vehicle back to the ground and/or reduce its speed to reduce the seriousness of an incident. Indicators notify the driver of the imminent or current deployment of corrective action, an accident, and/or the relative safety of various paths forward. Various implementations of this system and method reduce and/or eliminate race vehicles from reaching a catch fence, barrier, or other objects that pose great risk to both the driver and spectators.

Claims

1. An active monitoring and accident mitigation system and method for race vehicles that responds to a vehicle'"'"'s physical attitudinal status by modifying the forces on the vehicle to keep it on the ground and/or reduce its speed that includes:

at least one or more sensors that provide data for a vehicle'"'"'s physical attitudinal status,

at least one or more devices that alter the forces on a vehicle,

at least one local control module that compares sensor data to attitudinal criteria,

at least one local and/or remote monitoring system that provides oversight to the local control module, and

at least one local control module that provides one or more actionable signals to one or more attitudinal and air forces management devices.

2. The vehicle of claim 1 may take the form of a car, truck, boat, motorcycle, and other modes of transportation used in racing.

3. The devices of claim 1 that act on the vehicle in a manner that the net attitudinal forces on the vehicle minimize the potential for the car to go airborne, while assisting in returning it to the ground and/or to reduce the vehicle'"'"'s speed via either triggered or deployed devices, solely, or in coordination with other active and passive devices, that alone, or in combination, employ or induce various resultant forms of air action, including, but not limited to, downdraft, side draft and drag.

4. The devices of claim 3 that act upon the vehicle that may take the form of parachute(s), flap(s), wings, wings that change position, airbags, and/or controlled application of the vehicle braking systems, alone or in conjunction with other on-board systems.

5. The sensors of claim 1 that detect one or more characteristics of the vehicle including loft, angle, pressure, distance, structural stress, vehicle location, speed, and or change in direction.

6. The sensors of claim 5 that can be mechanical or electronic and may be on-board the vehicle or in its proximity, such as on other vehicles or in or around the course and its racetrack.

7. The mechanical sensor of claim 6 that may take the form of pressure plates that switch state based on a pressure, a flap that changes position, or a physical device that detects damage.

8. The electronic sensor of claim 6 that may take the form of instruments that include, but are not limited to, those that measure air pressure under the vehicle, distance of the vehicle from the ground, angular momentum sensed by an accelerometer, or gyroscopic inputs.

9. Information systems, using a variety of presentation methods, including, but not limited to gauges, lights, flat panel displays, and the like, on a vehicle of claim 1 that alert a driver just before or when a corrective vehicle physical attitudinal action is or is about to be taken, or that a hazard is present on the track, and how to avoid it or minimize its effect.

10. Data that is obtained from the one of more sensor(s) of claim 1 that is interpreted by a local and/or a remote software system, operating in either a local or remote computing hardware system, or both, in the combined form, a control module, that compares the information against stored, or real-time developed, vehicle physical attitudinal status criteria appropriate to the vehicle'"'"'s current status.

11. A control module of claim 10 that may take the form of mechanical linkage, electrical circuits, pneumatic and/or hydraulic circuits, or electronic systems.

12. The electronic control module of claim 10 that may take the form of programmable circuitry that compares sensor data to criteria and then triggers an output to a secondary device that responds.

13. The sensor data of claim 10 that may be from sensors on the vehicle, on another vehicle, or in or around the course and its racetrack.

14. The criteria of claim 10 that are fixed or configurable values that are compared against the data from one or more sensors to determine when devices should be actuated or deployed.

15. The criteria of claims 12, 13, or 14 that may be fixed or can be dynamically changed based on conditions such as vehicle speed and location.

16. The location-based criteria of claim 15 that may be programmed to ignore data from areas of a course with known disturbances to a vehicle, such as a curb that bounces it off the ground.

17. The location-based criteria of claim 15 or 16 that may also be used to trigger the system when a vehicle is detected to be off course.

18. The speed-based criteria of claim 16 that may be used to enable or disable the system for speeds above or below a specified value.

19. The devices of claim 3 that may also be triggered by the driver of the vehicle.
